Abstract | The IEEE 802.16 standard for broadband wireless metropolitan area network supports diverse real time and non-real time services. The standard defined the contention-based bandwidth request mechanism for the nonreal time (nrt-PS) and Best-Effort (BE) services. Before using the resource of base station (BS), the mobile station (MS) or subscriber station (SS) should send the bandwidth request (BW-REQ) in the allocated contention time interval. For avoiding collision, the standard supports truncated binary exponential backoff resolution. However this mechanism works inefficiently while the network traffic is overloading, and then the result will cause MSs waste power. In this paper we propose a new mechanism at MS, for BE service, to help the MS send the bandwidth request more efficiently and also avoid the traffic peak. By using the mechanism, the MS sends the bandwidth request in the low loading time and it reduces the power consumption of the MS. Additionally, the method balanced the burst of traffic loading and smoothed the traffic loading that brings the bandwidth request efficiency and higher power utilization. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
